Nahua Numbering System

This document, or codex, is a precise accounting in graphic images
and recorded testimony of many of the products made by the people
of Huexotzinco and paid as tribute. These products included corn
(maize), turkeys, chili peppers, and beans, as well as bricks, lumber,
limestone, and woven cloth. The accountants also included the amount
of gold and feathers used to produce a banner of the Madonna and
Child for a Spanish military campaign. This representation of the
Madonna and Child is one of the earliest to be produced in the Americas.
